• ffmpeg video slideshow only takes first image

  14 décembre 2018, par Erhan

  I wanted to create an .mp4 video with a framerate of 1 fps out of 10 images. I followed https://trac.ffmpeg.org/wiki/Slideshow and got to (my images are in the folder I am running the command from and are name img000.png, img001.png, etc.)

  path_to_ffmpeg\ffmpeg.exe -framerate 1 -i img%03d.png output.mp4

  However only the first image is taken to the video and it only shows one image !

  After trying multiple permutations of -framerate and -r options and positions of the options, I did not recieve any better results.

  Does anyone know what might have gone wrong even in this simple case ? Thanks.
